题型：不详难度：来源：

We would have to put off the visit to the Water Cube________ it rain tomorrow.

A．Would

B．Were

C．Should

D．Could

答案

C

解析

试题分析：考查虚拟语气。此题省略了if， 只能提前would.还原后的句型为 If it should rain tomorrow ,We would have to put off the visit to the Water Cube .在这种对将来的假设条件句中，可用一般过去时、were to do、should do 这三种形式，没有would do 结构。句意：如果明天下雨的话，我们将不得不推迟参观水立方。故C正确。
